Cooking device with light pattern projector and camera
First Claim
1. A cooking appliance, comprising:
- a cooking chamber having a loading opening which is closable by a door;
a light pattern projector arranged in a fixed manner relative to the cooking chamber and configured to generate and radiate a light pattern into a region of the cooking chamber;
a camera for capturing images from the region being irradiated by the light pattern projector even when the cooking chamber is closed, said camera being arranged in a fixed manner relative to the cooking chamber;
an analysis facility coupled to the camera and configured to perform light pattern analysis of the light pattern irradiated into the region of the cooking chamber, the analysis facility configured to repeatedly calculate, based on the light pattern analysis of the light pattern, a three-dimensional shape of an object located in the region of the cooking chamber being irradiated by the light pattern projector during operation of the cooking appliance; and
a muffle having predefined calibration markings in the muffle for delimiting the cooking chamber, wherein the analysis facility is configured to use the predefined calibration markings to perform a calibration.

Abstract
A cooking appliance includes a cooking chamber having a loading opening which is closable by a door. A light pattern projector is arranged in a fixed manner relative to the cooking chamber and configured to generate and radiate a light pattern into the cooking chamber. A camera captures images from a region being irradiated by the light pattern projector when the cooking chamber is closed, and is arranged in a fixed manner relative to the cooking chamber, Coupled to the camera is an analysis facility which repeatedly calculates a three-dimensional shape by light pattern analysis of an object located in the region being irradiated by the light pattern projector during operation of the cooking appliance.
